ANTIFREEZE SAVER Filed Feb. 21,1935 2 Sheets-Sheet 2 Inventor Attorney Patented Nov. 19, 1935 UNITED STATES PATENT OFFICE 2 Claims.

' l vide a device of the character referred to that is very efficient in operation, that has very few parts likely to need repair, that is very compact in arrangement and comparatively inexpensive to manufacture.

With the foregoing and other objects in view, the invention consists of a novel construction, combination and arrangement of parts as will be hereinafter more specifically described and illustrated in the accompanying drawings wherein is disclosed an embodiment of the invention, but it is to be understood that changes, variations and modifications may be resorted to without departing from the spirit of the claims hereunto appended.

In the drawings wherein like reference characters denote corresponding parts throughout the several views;

Figure 1 is a vertical section of one form of the device in accordance with the present invention when assembled with an automobile radiator cap,

Figure 2 is a front elevation thereof,

Figure 3 is a fragmentary vertical section through the forward end of an automobile and radiator showing another form of the invention built directly into the water chamber of an automobile radiator.

Referring to Figures 1 and 2 of the invention wherein the device is shown assembled on the cap of an automobile radiator, 5 indicates an internally threaded flange of the radiator cap and 6 indicates the crown thereof. The numeral I indicates the vertically arranged tubular shell enclosed by a bottom wall 8 and formed with a rearwardly directed elbow 9 at the top of the shell which elbow projects through and is secured to the crown 6 of the radiator cap. Elbow 9 is open at It at the rear projecting end thereof as this forms an outlet for the current of air.

The outer shell I when the cap is attached to the radiator A depends into the water compartment II of the radiator as will be clearly understood by referring to Figure l of the drawings. In the radiator A is the overflow pipe I2 by which excessive water in the water chamber H and any vapors escape into the air.

The inlet funnel is indicated at I 3 and consists of a vertically arranged tube mounted concentrically within the larger outside shell 1 and this vertical tube is open at the bottom as at M 0 and terminates above the bottom wall 8 of the outer shell thereby allowing currents of air to strike the bottom wall and flow out of the outer shell I through the rearwardly directed outlet opening Ill. Funnel 13 has an elbow l5 at the upper end which extends through an opening [6 5 in the wall of outer shell I and through an opening I! in the crown 6 of the radiator cap. On the forward end elbow I5 is open as at I8 whereby an air current passes through the funnel [3 when the vehicle is moving forwardly and passes out 10 of the outlet opening I0, and this air current cools the vapors in the water compartment I l of the radiator thereby condensing the vapors that would otherwise escape through the overflow pipe I2. 15

In that form of the invention illu trated in Figure 3 the device is assembled directly in the water chamber II of the radiator A where the outlet opening l0 receives the suction from the fan 20 on the internal combustion engine of an 20 automobile (not shown). In the arrangement of the device as shown in Figure 3 of the drawings there is a flange 2| around the inlet opening I8 which may be secured to the forward wall 22 of the radiator A by any suitable means such as 25 welding. Likewise there is a flange 23 around the outlet opening ill of the outer shell I which is secured to the rear wall 24 of the radiator A. In all other respects, the device is substantially the same as is shown mounted directly on the radiator cap in Figures 1 and 2 of the drawings.

From the foregoing it will be seen that since the outer shell I depends into the water compartment ll of the radiator, currents of air passing 35 through the funnel I3 strike the bottom wall 8 of the outer shell and set up a countercurrent of air which passes up the outer shell and out through the outlet opening Ill, elbow I5 being directed forwardly and elbow 9 being directed 40 rearwardly for this purpose.

Having thus described the invention, what is claimed as new is:

l. The combination with a radiator including a Water receptacle of a tubular shell connected with 45 the radiator and depending into the water receptacle, said shell terminating in an open outlet elbow, and an inlet funnel extending into the shell formed with an inlet elbow directed in opposition to the outlet elbow. 5o

2. The combination with a radiator including a water receptacle of a tubular shell connected with the radiator and depending into the water receptacle, said shell terminating in an open outlet elbow, an inlet funnel extending into the 55 shell formed with an inlet elbow directed in opposition to the outlet elbow, and a portion of the inlet funnel arranged in concentric relation to the shell.
